Small fix to the Slackware package maker script.
Small changes to test footbot lua
Removed call to CSimulator::Destroy() in case of fatal errors because it is likely to spawn errors on its own.
Fixed bug in the removal logic of the entities. Memory corruption happened whenever a robot was removed, for instance in the random distribution of robots.

Fixed the ids of the e-puck and foot-bot components.

Fixed a little memory leak - when removing unmovable embodied entities the bounding box was not deleted.

Test with different experiments and with Valgrind, everything seems fine now.
